Candy shouldn't try to connect to localhost just by requiring it

[anaisbetts]

Spinning up an irb prompt and running:

require 'candy'

Causes the Candy module to create a MongoDb connection to localhost, without actually using any Candy objects. Here's the stack, I'm using a git submodule that is a mirror of this repo:

➜ Istoria git:(version_two) ✗ bundle exec irb
irb(main):001:0> require 'candy'

Good catch! You're completely right -- the intention was to have lazy everything, and not make any connections until the first data operation is performed. But I was sloppy and didn't test it on a machine that didn't have MongoDB running, so I didn't notice that an attempt to set a collection name was causing a cascade of references. I also think the "require everything" approach in the main candy.rb file was too greedy.

It's fixed now. Please try the latest version (gemmed and tagged as 0.2.6) and let me know if you still have any problems. Thanks very much for pointing this out.
